Abstract
Provided is a platform positioning system including a platform and an elevator, wherein a cabin of the elevator is movable along a wall segment of a building, wherein the platform positioning system further includes a first attachment mechanism for releasably attaching the platform to the cabin, wherein the motion of the cabin and the platform are coupled to each other when the platform is attached to the cabin, and a second attachment mechanism for releasably attaching the platform to the wall segment.
Claims16
A platform positioning system comprising:
- a platform;
- a plurality of tubular tower segments, wherein two adjacent tubular tower segments are attached to each other on flanges at axial ends of the tubular tower sections, the flanges extending radially inwardly;
- an elevator comprising a cabin having a hole on at least one side wall, and/or a top section and/or a bottom section of the cabin, wherein the cabin of the elevator is movable along a wall segment of a building formed by the plurality of tubular tower segments;
- a first attachment means configured to be inserted into the hole of the cabin for releasably attaching the platform to the cabin, wherein a motion of the cabin and the platform are coupled to each other when the platform is attached to the cabin;
- and
- a second attachment means configured to rest on a support section of the flanges for releasably attaching the platform to the wall segment;
- wherein the platform comprises an opening that allows the cabin to completely pass through the opening such that a range of motion of the cabin is not limited by a position of the platform;
- and
- a control unit configured to switch the platform positioning system between a first operational state wherein the platform and the wall segment are disconnected, and the platform is attached to the cabin by the first attachment means being inserted into the hole of the cabin, and a second operational state, wherein the platform and the cabin are disconnected and the platform is attached to the wall segment by the second attachment means resting on the support section of the flanges;
- wherein, in the second operational state when the cabin is disconnected from the platform, the platform is attached to the wall segment and supported at a position within the building based on the second attachment means.
A method for operating a platform position system with a platform and an elevator, the platform positioning system comprising a plurality of tubular tower segments, wherein two adjacent tubular tower segments are attached to each other on flanges at axial ends of the tubular tower sections, the flanges extending radially inwardly, the elevator comprising a cabin having a hole on at least one side wall of the cabin, and/or a top section and/or a bottom section of the cabin, wherein a transportation of the platform by the cabin of the elevator moving along a wall segment of a building comprises:
- attaching the platform to the cabin by a first attachment means configured to be inserted into the hole of the top section of the cabin,
- moving the cabin together with the platform to a position where the platform is desired,
- attaching the platform to a wall segment by a second attachment means configured to rest on a support section of the flanges, and
- disconnecting the platform and the cabin, wherein the platform comprises an opening that allows the cabin to completely pass through the opening such that a range of motion of the cabin is not limited by a position of the platform;
- wherein, when the cabin is disconnected from the platform, the platform is supported at a position within the building based on the second attachment means;
- wherein, when the cabin is connected to the platform, the cabin and the platform are both supported within the building by a rope connected at one end to the cabin and at another end to an electric motor disposed at a top of the building;
- wherein, when the cabin is located above the platform, the rope is above the platform, and when the cabin is located beneath the platform, the rope passes through the opening and extends beneath the platform.
